KABUL, Afghanistan (AP) — Afghan authorities say one person has been killed and six hurt in a clash between Sunni and Shiite students at Kabul University.
An Associated Press reporter at the scene said Shiite and Sunni students started fighting and by evening, several hundred more people joined the melee.
Damage was reported to buildings at the university and classes have been canceled for 10 days.
Witnesses say the clash was related to Ashoura, the commemoration of the 7th century death of the Prophet Mohammad's grandson.
Other gatherings in the Afghan capital marking the Shiite holy day were peaceful. But last year, a suicide bomber on foot struck worshippers at a Shiite shrine in Kabul, killing at least 80 people.
Some Sunni extremists consider Shiite ceremonies to be heretical.
Elsewhere in Afghanistan, NATO says a service member with the international military coalition was killed today in an insurgent attack in the south.
So far this year, 379 NATO service members have died in Afghanistan.
